FIBER-TREATING ENGINE.

Specification of Letters Patent.

Patented Aug. 28, 1h06.

Application filed January 15, 194. Serial No. 189.197.

To all whom it may concern:

Be it known that I, SOLOMON R. WAGG, a citizen of the United States, residing at Apleton, in the county of Outagamie and tate of Wisconsin, have invented new and useful Improvements in Fiber-Treating Engines, of which the following is a specification. 1

This invention relates to improvements in machines for treating fiber for use in the manufacture of pa er, and has for its object to rovide a mac 'ne capable of subjecting the ber to the beating action of two sets of grindin or beating members, one of which is relative y softA as compared with the other and movable with respect thereto. The

- specific object of the invention relates to the provision of an engine having cooperating' wooden and stone bars.

In order that the invention may be clearly understood, I have illustrated the same in the accompanying drawing, in which the fi ure represents a cross-section through the ro l and bed-plate of an ordinary Holland or beating engine.

1 represents the roll or cylinder of the en.- gine, 2 the shaft upon which it is supported to rotate, and 3 a series of woodenbars which are secured at regular intervals around the roll 1 in longitudinal grooves 4, provided for the purpose and secured in place in any'prepred manner, as by Wedging, bolting, or the 5 indicates the bed-plate, which is composed of stone bars 6, w 'ch may be held in position by clamping them between side plates 7, of metal or any other preferred material, by means of bolts 8.

, I find that by subjecting fiber to the action of two sets of bars, one of which is relatively soft as compared with the. other, that the fiber` isreduced or drawn out in a gentle, smooth; and easy manner, and there is practically an entire absence of all cutting of the fiber, which latter is invariably the case where metal bars have been employed on the roll and in thebed-plate, as has heretofore been customary". The result is that the nished product Will produce paper of a high degree of uniformity both as to smoothness words, the action of the wooden bars coperand toughness-that is to say, the fibers constituting the sheets of paper will be relatively long as compared with the fibers of paper which have been treated to the action of me'tal blades, and thus the parts of the finished sheet of paper will be more firmly bound together, Whereas when the fibers are short the paper Will be more brittle and will consequently break more readily. In other atin with the stone bedlate will bev to aw the 'bers outas contra istinguished to cutting them. i

While I have described my invention in connection with an ordinary Holland or beating engine, I wish it distinctly understood that I may use the same inv connection With what are known as refining or Jordan engines.

It will be readily apparent that I can vary the arrangement of the Wooden and stone bars (from that described herein and illustrated in the drawing Without departing from the spirit of my invention. Thus, for instance, the wooden bars may be placed in the bed-plate 5 and the stone bars in the roll the wooden and stone bars can be placed in the roll and wooden and stone bars can be placed in the bed-plate.

Having thus fully described my invention, what I claim as new, and desire to secure by `1. A fiber-treating engine, for use in the manufacture of paper, provided with coper- Aating Wooden and stone bars, one set of said bars being arranged to be rotated in proximity to the other set.

2. In a fiber-treating engine, for use in the manufacture of paper, in combination with a rotary member provided with wooden bars, a coperatingstationary member presenting a stone surface. p

In testimony whereof I have hereunto set my hand in presence of two subscribing wit'- nesses. i
